    Subject[patch 4/6] zfcp: Remove SCSI devices when removing complete adapter
    From: Christof Schmitt <christof.schmitt@de.ibm.com>

    The common I/O layer can call remove a handler to inform zfcp
    that a device disappeared. The handler zfcp_ccw_remove then
    removes all unit, port and the adapter data structures. Removing
    the units requires that the SCSI devices are removed first.
